    <br/>ETL引擎图的的鼠标操作逻辑描述
    <br/>
    <br/>作者采用一种极为简练的傻瓜操作方法对引擎画布有效的鼠标操作, 首先, 在节点的树形界面操作,
    鼠标左键为确定当前选择, 右键为当前选择的功能展开. 举例 鼠标左键点击选中一个节点, 右键点击于是
    出现弹窗, 点击add添加, 于是右边主画布画出节点图形.
    <br/>
    <br/>其次, 画布的节点操作, 鼠标左键的功能为选中一个节点, 持续鼠标左键按下可以进行节点的移动
    拖拽功能. 鼠标右键的功能包含非移动拖拽和移动拖拽, 在选中一个节点后, 非移动拖拽, 可以弹出节点
    操作功能jframe面板, 如配置configuration, 执行execute, 展示 view, 删除当前节点 delete,
    删除当前节点的关联链接箭头线 delete. 鼠标左键点击功能项可以进行节点详细操作. 关于右键的持续按
    下移动拖拽为节点的箭头链接拖拽操作, 指在非移动节点的情况下, 进行拖拽所指引的目标节点进行连线.
    细节为右键拖拽需要将鼠标指向 节点的关联点区域, 如图中节点左侧的上中下链接点.

    <br/>Implements of mouse manipulations of ETL unicorn.
    <br/>
    <br/>The author adopted a succinct way of effect mouse manipulations
    of ETL unicorn. To keep It way of simple, firstly built the tree
    manipulations where to make a classify of ETL nodes. Once did an
    expanded window to add the node into a canvas board by mouse clicks.
    The mainly canvas will present this related node branch and Its
    manipulations by mouse-click. The left-mouse-click could well choose
    the ETL node, to make a moving and dragging of the related node. The
    right-mouse-click could well drag the ETL node arrow, to make a
    line-link, which connected to the object node. The details of line
    connection, means It kept an endpoint of arrow which aimed to the
    hook-area of each node. For example, the node in picture, which
    contained three hook-areas of up, middle and bottom on left side. Also,
    the right-mouse-click with non-moving condition, could well click out a
    jumped JFrame component. This component contained four operations of
    configuration, execute, view and delete, to the continued
    manipulations.
